Okay, this isn't new, in fact it's pretty ancient. The chart was originally found inside of a royal tomb in Beijing. It was developed by the Chinese because most wanted boys since girls were not considered "useful" and were seen as an expense. So, to try to increase their chances of having a boy this chart was developed. The Chinese Gender Chart uses the mother's age at conception and the month of conception to determine whether she will have a boy or a girl and it is said to be OVER 90% ACCURATE.
I think this chart is fascinating. I have yet to come across a person that it didn't work for! I have tested it on all of my family and friends... 100% so far! I have a few preggo friends and I can't wait to see if theirs are right too!
